Taw qhia

2-Nitropropane hmoov. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-nitropropane:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- Solubility: Soluble hauv cov kuab tshuaj organic xws li ethanol, ether, acetone, thiab lwm yam

 

Siv:

- 2-Nitropropane feem ntau yog siv los ua ib feem ntawm cov khoom tawg thiab cov tshuaj tiv thaiv, thiab feem ntau yog siv los ua cov khoom tawg thiab foob pob hluav taws.

- Nws kuj yog siv los ua qhov pib tseem ceeb rau kev sib txuas ntawm cov organic sib txuas rau kev npaj lwm yam tshuaj.

 

Txoj kev:

- 2-Nitropropane tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm glycerol thiab nitric acid. Glycerol ntxiv rau nitric acid, ua raws li cov tshuaj tiv thaiv cua sov, uas thaum kawg muab 2-nitropropane.

 

Cov ntaub ntawv kev nyab xeeb:

- 2-Nitropropane yog qhov sib xyaw ua kom tawg thiab yuav tsum tau ua tib zoo saib xyuas kom tsis txhob raug cov nplaim taws xws li qhib nplaim taws, kub kub, lossis hluav taws xob.

- Kev kub hnyiab tuaj yeem tshwm sim ntawm daim tawv nqaij thiab qhov muag, hnav hnab looj tes tiv thaiv thiab tsom iav thaum ua haujlwm.

- Khaws kom deb ntawm oxidants thiab combustibles thaum siv los yog khaws cia, thiab ua kom muaj cua zoo.

-Thaum noj tshuaj tsis haum lossis nqus tau, nrhiav kev kho mob tam sim ntawd thiab muab daim ntawv qhia kev nyab xeeb rau koj tus kws kho mob siv.

 

Siv 2-nitropropane nrog ceev faj thiab ua raws li cov txheej txheem kev nyab xeeb thaum ua haujlwm.
